Referring to the discussion here: https://forum.cloudron.io/post/112663 and after a very interesting update to the app (adding OCR for attachments) that was just released:

• Summary:Open Archiver provides a robust, self-hosted solution for archiving, storing, indexing, and searching emails from major platforms, including Google Workspace (Gmail), Microsoft 365, PST files, as well as generic IMAP-enabled email inboxes. Use Open Archiver to keep a permanent, tamper-proof record of your communication history, free from vendor lock-in.

Key features:

• Universal Ingestion: Connect to any email provider to perform initial bulk imports and maintain continuous, real-time synchronization. Ingestion sources include:

  • IMAP connection
  • Google Workspace
  • Microsoft 365
  • PST files
  • Zipped .eml files
  • Mbox files

• Secure & Efficient Storage: Emails are stored in the standard .eml format. The system uses deduplication and compression to minimize storage costs. All data is encrypted at rest.

• Pluggable Storage Backends: Support both local filesystem storage and S3-compatible object storage (like AWS S3 or MinIO).

• Powerful Search & eDiscovery: A high-performance search engine indexes the full text of emails and attachments (PDF, DOCX, etc.).

• Thread discovery: The ability to discover if an email belongs to a thread/conversation and present the context.

• Compliance & Retention: Define granular retention policies to automatically manage the lifecycle of your data. Place legal holds on communications to prevent deletion during litigation (TBD).

• File Hash and Encryption: Email and attachment file hash values are stored in the meta database upon ingestion, meaning any attempt to alter the file content will be identified, ensuring legal and regulatory compliance.

• Comprehensive Auditing: An immutable audit trail logs all system activities, ensuring you have a clear record of who accessed what and when (TBD).

• Notes: OpenArchiver has full-text search for attachments based on Meili Search and Apache Tika (OCR!). I don‘t know any other open sourced mail archiver that does that…
